Thanks to @jiegec, x86_64-linux-musl-gcc is now working on rCore! 🎉

But now it takes nearly 10s (on QEMU) to build a simple C source file.
It's time to find the bottleneck and do some optimization!

  • implement delay mapping files
  • implement vfork

Optimizing gcc is a really difficult work to do!
